The 40 Best Windows 8.1 Apps

Adobe Photoshop Express

Free
Of course, you can run the big Kahuna, Photoshop CC itself on a Windows 8 PC (though not on an ARM-based RT tablet), but for quick fixes and image enhancements, this free app will do in a pinch. A clear intro slideshow shows you how this app syncs with Adobe's Revel cloud photo service (now built into most of the company's other apps), as well as about the app's 15 Instagram-style filters and auto brightness and color corrections. For more control over adjustments, you can use iPhoto-like sliders to tweak image tonalities. If the 15 included filters don't do it for you, you can purchase 20 more for the low price of $2.99; some of these are very cool, such as Dream, Orton, and Superpunch. Once you've got an image looking supercool, you can not only upload it to Revel, but also share on Facebook.
